final push: senior year

Will doing things such as getting a job, playing an extra sport, improve academic deficiencies from the junior year (I have all A/B's except but calculus- all IB courses), and/or more volunteering really help to earn that appointment?

It's not just about punching your ticket w/ a whole bunch of extra curricular activities it's about LEADERSHIP. Are you a team captain of a sports team or club. It's about showing you can be RESPONSIBLE. So if you are taking a job just so you can have one more thing to put on your resume, try to work toward being a shift supervisor or something that shows not only you're responsible but another leadership opportunity.

As a BGO I've interviewed several candidates and I see they have a jam packed resume w/ all the things they are involved in but they are just a member. When I ask them to describe what leadership roles they've had in X activity I get a deer in the headlights look.

02 is correct; make whatever you do count for something. It is not too late to improve your situation, but you must make positive use of this time. Among other things you might try to improve your calculus grades; you can count on getting a major dose of calculus at any of the SA's. Have you taken chemistry or physics yet? Have you maxed out the SATs or ACTs? Prepare to retake them. Get a job where you will have responsibility and leadership opportunities and take advantage of that opportunity. You need to compile some real leadership credentials if you don't already have them.
Make the time this summer really count towards making yourself the absolute best candidate you can become, and best wishes to you in your efforts.

I would suggest asking about leadership opportunities in some of the groups with which you are already involved. During his junior year, my son explained his future plans to his soccer coach and our director at the local community theater. He was very active in both arenas. Both the coach and the director gave him increased responsibility until he earned a position as team captain in soccer and musical director for several shows at the theater. Showing your interest by asking can go a long way toward gaining leadership opportunities and experience!

Oh, and when looking for a job, think outside the box. DS taught piano lessons rather than looking for a job outside the home. He could choose his own hours and got leadership and business experience. Best of luck to you as you pursue your dreams!!!
